无服务器: httpApi中的请求参数

Question

这是我的serverless.yml部分的样子：

my-function:
      - http:  # <---- http
          method: POST
          path: /my-function/{id}
          request:
            parameters:
              paths: id:true

我想使用AWS HTTP-API。因此，我将http ->改为httpApi，如下所示：

my-function:
      - httpApi:  # <---- now httpApi
          method: POST
          path: /my-function/{id}
          request:
            parameters:
              paths: id:true

但是我得到了这个错误信息：

Serverless: Configuration warning at 'functions['my-function'].events[2].httpApi': unrecognized property 'request'

如何在httpApi节中定义URL参数？

Answer 1

其中一个建议是，我使用serverless 4天后才意识到，我需要首先了解Lambda和整个架构。如果你对整个事情都是新手，我会先跳过无服务器框架，然后再回头看看，因为它非常有用。可以回答您的问题：

这是基本的httpApi格式：

functions:
  params:
    name: myLambdaName
    handler: index.handler
    events:
      - httpApi:
          path: /v1/test
          method: get

这是你需要的official documentation。

这是serverless.yml文件中所有内容的样子，我添加了一些注释，以便您了解发生了什么：

service: my-express-application

frameworkVersion: "2"

provider:
  name: aws
  stackName: myName # Use a custom name for the CloudFormation stack
  runtime: nodejs12.x
  lambdaHashingVersion: 20201221
  stage: v1 # your default stage, the one lambda and all services define here will use
  region: us-east-1 # <- This is your regeion, make sure it is or change it
  httpApi: # rdefining your existing api gateway
    # id: xxx # id of externally created HTTP API to which endpoints should be attached. This will allow you to use it but this lambda can't modify it
    payload: "2.0" # the latest payload version by aws is 2.0
    name: "v1-my-service" # Use custom name for the API Gateway API, default is ${opt:stage, self:provider.stage, 'dev'}-${self:service} you will only be able to modify it if you created the api using this stack and not referencing it above
    cors: false # Implies default behavior, can be fine tuned with specficic options
  timeout: 10
  logRetentionInDays: 7 # Set the default RetentionInDays for a CloudWatch LogGroup

functions:
  params:
    name: myLambdaName
    handler: index.handler
    events:
      - httpApi:
          path: /v1/test
          method: get

我不知道是不是太晚了，但这就是答案

1. 你不必使用"request..."

handler: bin/function events: - httpApi: path: /function/{id} method: post

代码中的

1. (本例中为go)，只需通过以下方式调用参数即可

id:= request.PathParameters["id"]
